IMPROVEMENT IN BRICK-MACHINES.

Specification forming part of Letters Patent No. 167,147, dated August24, 1875; application filed July 27, 1875.-

To all whom it may concern:

Be it known that I, DANIEL W001), of Arbela, in the county of Scotlandand State of Missouri, have invented certain new and useful Improvementsin Brick-Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it,reference being had to the accompanying drawings, which form part ofthis specification.

My invention relates to an improvement in brick machines; and itconsists in the arrangement and combination of devices that will be morefully described hereinafter.

Figure 1 is a vertical section of my invention. Fig. 2 is a plan, andFig. 3 an inverted section of the same.

a represents an ordinary rectangular box, of any desired construction orsize, in the center of which is placed the vertical shaft 1), to theupper end of which shaft is secured the sweep or lever c. Extending outfrom the. sides of this shaft are the stirrers d, and to the lower part,just above the floor e, is secured the false floor 9, that revolves withthe shaft, the said floor resting upon two of the stirrer-s, andextending a little over half-way around the shaft. Projecting out andupward from under one end of this false floor is the spiral ly-curvedmetal plate h, which presses the clay downward into the molds i. In theside of the floor 9 there is cut a recess to receive the molds, and aslight distance below the floor is formed a frame-work, to support themolds while in position. This frame-work consists of the bar j, thatruns parallel with the edge of the frame a, the two bars 3 placed atright angles thereto, and having their front ends projecting out beyondthe frame, so as to form a support out in front, and the curved metalbar or plate 1 that supports the rear ends of the bars 3. The lower endof the shaft b extends down through the floor g, and to this lower endis secured a cam-shaped lever, 4, which, as. the shaft sweeps aroundafter the curved plate h has pressed the clay into the molds, pushes themolds out on the projecting ends of the rods or bars 3, where it isready for delivery. As the top of the mold comes just flush with the topof the floor g, as the molds are pushed outward, the front side of thebox cuts away all of the clay that remains above the top of the molds.The false floor g prevents the clay from running out at the hole for themolds when the molds are taken away.

Having thus described my invention, I claim- 1. In a brick-machine, thefalse floorg, secured to the shaft 12 so as to revolve with it and closethe opening through the floor over the molds when the molds are takenaway, to prevent the clay from running out, as described.

2. The combination of the false floor y, secured to the revolving shaft1), curved plate h, for forcing the clay into the molds, and lever 4.,for pushing the molds from the supporting-frame 1 3, as and for thepurposes specified.

In testimony that I claim the foregoing I have hereunto set my hand this7th day of July, 1875.

hi DANIEL WOOD.
